Vaccines

Junk Science? Number 132: Vaccination beats natural Immunity?

The high cost of vaccination has been driven by vaccines wasted on those who simply did not need them and people, who posed  no threat to third parties, losing their jobs.

Johns Hopkins experts in global public health, infectious disease, and emergency preparedness have been at the forefront of the international response to COVID-19. They have a Website devoted to Covid – the Coronavirus Resource Centre, so you would expect to be able to trust and rely on what this top Medical School tells us. 

On January 26th, Dr Martin Mackary, a Professor at the Johns Hopkins School of Medicine wrote this in the Wall Street Journal. It should end the debate about ‘Natural Immunity or vaccination’ forever, and fake scientists and the media should be ashamed of their role in misleading the public.

Public-health officials ruined many lives by insisting that workers with natural immunity to Covid-19 be fired if they weren’t fully vaccinated. But after two years of accruing data, the superiority of natural immunity over vaccinated immunity is clear. 

By firing staff with natural immunity, employers got rid of those least likely to infect others.

It’s time to reinstate those employees with an apology.  For most of last year, many of us called for the Centers for Disease Control and Prevention to release its data on reinfection rates, but the agency refused. Finally last week, the CDC released data from New York and California, which demonstrated natural immunity was 2.8 times as effective in preventing hospitalization and 3.3 to 4.7 times as effective in preventing Covid infection compared with vaccination.  

Yet the CDC spun the report to fit its narrative, bannering the conclusion “vaccination remains the safest strategy.” It based this conclusion on the finding that hybrid immunity—the combination of prior infection and vaccination—was associated with a slightly lower risk of testing positive for Covid. 

Vaccinating those with immunity doesn’t show benefits

But those with hybrid immunity had a similar low rate of hospitalization (3 per 10,000) to those with natural immunity alone. In other words, vaccinating people who had already had Covid didn’t significantly reduce the risk of hospitalization. 

Similarly, the National Institutes of Health repeatedly has dismissed natural immunity by arguing that its duration is unknown—then failing to conduct studies to answer the question. 

Johns Hopkins research

Because of the NIH’s inaction, my Johns Hopkins colleagues and I conducted the study. We found that among 295 unvaccinated people who previously had Covid, antibodies were present in 99% of them up to nearly two years after infection. We also found that natural immunity developed from prior variants reduced the risk of infection with the Omicron variant. 

Meanwhile, the effectiveness of the two-dose Moderna vaccine against infection (not severe disease) declines to 61% against Delta and 16% against Omicron at six months, according to a recent Kaiser Southern California study. In general, Pfizer’s Covid vaccines have been less effective than Moderna’s.

The CDC study and ours confirm what more than 100 other studies on natural immunity have found: The immune system works. The largest of these studies(1), from Israel, found that natural immunity was 27 times as effective as vaccinated immunity in preventing symptomatic illness.

None of this should surprise us. For years, studies have shown that infection with the other coronaviruses that cause severe illness, SARS and MERS, confers lasting immunity. In a study published in May 2020, Covid-recovered monkeys that were rechallenged with the virus didn’t get sick. 

Misinformation from Political Leaders

Public-health officials have a lot of explaining to do. They used the wrong starting hypothesis, ignored contrary preliminary data, and dug in as more evidence emerged that called their position into question. Many, including Rochelle Walensky, now the CDC’s director, signed the John Snow memorandum in October 2020, which declared that “there is no evidence for lasting protective immunity to SARS-CoV-2 following natural infection.” It also talked of how “We must protect our workforce and avoid long-term uncertainty”.

Destroying careers

Meanwhile, public-health officials recklessly destroyed the careers of everyday Americans, rallying to fire pilots, truck drivers and others in the supply-chain workforce who didn’t get vaccinated. And in the early months of the vaccine rollout, when supplies were limited, we could have saved many more lives by giving priority to those who didn’t have recorded natural immunity. 

The failure to recognize the data on natural immunity is hurting U.S. hospitals, especially in rural areas. MultiCare, a hospital system in Washington state, fired 55 staff members on Oct. 18 for being out of compliance with Gov. Jay Inslee’s vaccine mandate—and that was in addition to an undisclosed number of staffers who quit ahead of the vaccination deadline. The loss of workers contributed to a full-blown staffing crisis.

The Centers for Medicare and Medicaid Services took the hospital mandate national by decreeing that all medical facilities under its jurisdiction require vaccination for employees, including those with natural immunity. The Supreme Court upheld the rule on Jan. 13, the same day it issued a stay against a similar mandate from the Occupational Safety and Health Administration, which OSHA formally withdrew last Tuesday.

Science overcoming politics?

Connecticut has suspended its vaccine mandate for state employees, and Starbucks is rehiring employees fired for being unvaccinated. Other states and businesses should follow their lead. Politicians and public-health officials owe an apology to Americans who lost their jobs on the false premises that only unvaccinated people could spread the virus and only vaccination could prevent its spread. Soldiers who have been dishonorably discharged should be restored their rank. Teachers, first responders, and others who have been denied their livelihood should be reinstated. 

Everyone is essential
